Addenda value not showing in bank account

Hello -

I can confirm that the ACH addenda feature is live on our production account. Here is an example POST request.

{
"_links": {
  "source": {
    "href": < source funding source >
  },
  "destination": {
    "href": < destination funding source >
  }
},
"amount": {
  "currency": "USD",
  "value": "1"
},
"correlationId": < GUID of Transfer record >,
"achDetails": {
  "destination": {
    "addenda": {
      "values": [
        "ID_xxxxxx" //last six digits of GUID
      ]
    }
  }
},
"processingChannel": {
  "destination": "real-time-payments"
}
  }

The transfer is successfully initiated and completes. However, I’m not seeing this addenda (ID_xxxxxx) show up anywhere in the destination bank account. Is there anything wrong with this request? Will the addendum just not show up in some banks? Thanks.
